CLOSURE FOR PAEPER PACKAGES.

. or, which form a part of this specification.

My invention relates to a box or bottle or package composed of paper or the like for containing solids, semi-liquids or liquids,more especially the latter,and is designed more particularly to furnish a cheap and simple closure or stopper for such package which shall be practically air-tight and, if desired, which can be so secured in place that it cannot be removed without destroy ing either the stopper or rupturing the package in such manner as to tend to prevent the Fraudulent second use of the package.

I attain these objects by means of the construction and arrangement of parts hereinafter described, and shown and illustrated in the sin le figure of the accompanying drawing, W ichis a central, vertical, sectional elevation of a package of the character indicated, with the stopper, hereinafter ret'erred to, in place.

The package or b0); orbottle A may be circular or angular in transverse section and when designed for use in containing liquids o1: semi-liquids is water-proofed, as with paraffin. The top or end of the package has therethrough a circular hole 2) which forms the mouth of the package. As a closure for this opening I employ a stopper 0 which is .formed from a disk of tough stout paper, cardboard or other suitable material, pressed.

or'otherwise formed into cup-shape and having a flange d. The stopper is coated all over with parafiin. In the coating operation,

the cup-shaped portion and the flange, retains a thicker deposit of paraflinthan the Patented May 5, rate.

remaining surfaces of the stopper, which do posit aids in the subsequent hermetic sealing of the vessel, as hereinafter described. The .cupis constructed to exactly fit the opening 7). The side and bottom of the cup extend into and through the opening 7) with the flange (Z restin upon and covering the margin of the mout as shown in the drawing. This cup-shaped device is coated with paraffin.

stopper is pressed fiat against the margin of the hole 7) so that the inner side of the flange Now With a suitable tool, prop-- erly heated, the fiange'of the cup-shaped adheres to the end of the package, thus forming a tightjoint. It .will be observed that the bottom of the cup is not flat but is formed with enough material to permit the radial expansion of the bottom of the cup without rupturing it.

In case it is desired to make the package non-refillable heated, is pressed into the cavity of the cuplike stopper and. the wall of the'cup, at its bottom, is permanently expanded, as illustrated in dotted lines in the drawing, so that the bottom of the stopper now becomes considerably wider than the opening and so that in opening the package the stopper orthe top of the'packa'ge, or both, will be visibly ruptured to such extent as to defeat a subsequent improper use of the package. v

The stopperhere.described is inexpensive and efiectivd and does not interfere with the packing of thesddvices one upon another. In practice,-tbe stopper 0, including the flanged, is covered with a seal secured to the top of the package which further tends to preclude the refilling of the packagewith spurious goods.

Having described: my invention, what I claim and. desire to secure by Letters Patent is,

A package of the described; character,

having an opening forming. a mouth therefor, combined with a closure for such mouth comprising a cup-shaped flanged parafiined a suitable tool, properly stopper, having an .expansible bottom, fitted In testimon whereof I afi x my signature in said mOfllth with itsfflairllge adhesivgly ekein presence 0 two witnesses.
